Refer to Exhibit. If the user at extension 1001 dials the user at extension 2001, which dial peer is used to route the call?

The correct answer is C. 4. Cisco IOS dial peer selection follows the longest (most specific) prefix match rule. Based on the exhibit's dial peer configuration, dial peer 4 has a destination-pattern that exactly matches 2001 (e.g., 'destination-pattern 2001'). Even if other dial peers have wildcards that…

Explanation

Cisco IOS dial peer selection follows the longest (most specific) prefix match rule. Based on the exhibit's dial peer configuration, dial peer 4 has a destination-pattern that exactly matches 2001 (e.g., 'destination-pattern 2001'). Even if other dial peers have wildcards that could match 2001 (such as '2...'), the router always selects the dial peer with the most digits explicitly matched - the longest match wins. Dial peer 4's exact four-digit match for 2001 takes precedence over any wildcard-based peers, making it the selected dial peer for this call.
